To @ZZ whom, 'it may con/cern; y Y

Be it known that we, HARRY P. MAsONand THOMAS HART, citizens of theUnited States, residing at Millwood, in the county of Fresno and Stateof California, have invented a new and useful Apparatus for HaulingLogs, of which the following is a specification.

The invention relates to improvements in apparatus for hauling logs.

The object of the present invention is to improve the means employed forhauling logs from woods to a mill over a chute or skid-road and toprovide a simple and comparativelyinexpensive apparatus of thischaracter of great strength and durability and of maximum capacityadapted to dispense with gearwheels and capable of enabling belts to beemployed-at all points for communicating Vmotion, whereby it is' adapted4to be run at a high rate of speed and at the same time maintain asteady strain-on the main cable, therebyincreasing the durability of thesame and lessening the cost of handling logs in this manner.

The invention consists in the construction and novel combination andarrangementV of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a plan View of an apparatus constructed inaccordance with this invention. Fig. 2 is a longitudinal sectional view.Fig.y 3 is a transverse sectional: view on the line 3 3 of Fig. 1. Fig.4 is adetail perspective view of one of the clutches.A

Fig. 5 is a detail sectional viewon the line 5 5 of Fig. 1.

Like numerals of reference designate corresponding parts in all theiigures of the drawings.

1 designates a supporting-frame composed of approximately rectangularlongitudinal and transverse portions and provided at'its front end Withbearings 2 and 3 for the recep- .tion of a transverse shaft 4, on whichis fixed a main drum 5, havinga main cable 6 wrapped around it, and thiscable, which isdesigned to be run out: by the ineanshereinafter.described, is'adapted to have a series of logs coupled to it, wherebythey aredrawn along a log-chute or skid-road and conveyed from woods toa mill. The main cable 6 is designed to be connected with either one ofa pair of supplemental cables 7 and 8 to forma reciprocatory carrier,which passes around a large sheave or pulley 9, designed to be anchoredo'rsecure'd at a suitable point from which the logs are to be hauled.The supplemental cables 7 and 8, which are designed to be lighter or ofless diameter than the main cable, as they are only subjected to thestrain of running the latter out to the logs, are wound or wrappedaround side drums 10 and 11, located at opposite sides of the frame, asclearly illustrated in Fig. 1 of the accompanying drawings. The sidedrums are thrown out of operation by the means hereinafter described,

when power is appliedvto thecentral or main.

drum in order that the supplemental cable may unwind freely while thelogs are being hauled to the mill, and the central or main drum isallowed to run free when either of the side drums is operated to wind upthe supplementalcable and run the main cable out for another load. I

The central longitudinal portion of the supporting-frame is providedwith longitudinal beams or sills 12 and 13, arranged in pairs and spacedapart to receive pulleys 14 and belts 15, extending from the frontpulleys 14 to a pair of rear pulleys 16, mounted on a central transverseshaft 17, carrying suitable clutches r 18 and 19, whereby the pulleys 14and 16 and the main drum may be thrown into and out of operation.V shaft17 is journaled in 'suitablebearings 20 Aand 2l 'of thelongitudinalsills or beams, and it has fixedto it a central pulley 23, which isconnected by a belt 24 with a drive-pulley 25 The cent-ral transverseclutchef an engine-shaft 26, carrying crank-disks 27 at its endsandconnected by suitable pitmen with cylinders (not shown) of an engine.Motion is transmitted from the drive-pulley 25 through the belt 24 tothe clutch-shaft, and the side belts 15 transmit the motion of theclutch-shaft to the front shaft 4, which carries the main drum.

The rear side pulleys 16 are loose upon the clutch-shaft, and they carryclutch members or portions 28, which are adapted to beengaged by thesliding clutches 18 and 19,mount ed on the shaft 17 at points betweenthe longitudinal sills 12 and 13 and adapted to be operatedsimultaneously by the means hereinafter described. The clutches 18 and19 IOO are secured to the shaft by means of suitable feathers or keys,and they are connected, respectively, to longitudinal levers 20 and 30by means of suitable collars arranged in grooves of the clutches andpivot-ed to the adjacent ends of the levers. The lever 2),which isadapted to be operated by hand, is fulcrumed near its front end, at 231,on a trans verse bar, and it is connected at a point in rear of thefulcrum by a rod 32 with the other lever 30, which is fulcrumed at itsrear end. hen the operating-lever 29 is oscillated, the sliding clutches18 and 19 are simultaneously moved to and from the rear side pulleys 1Gto engage them with and disen gage them from the clutch members 28.These clutch members or portions 28 of the clutch-pulleys 16 may beconstructed in any suitable manner to interlock with the slidingclutches 18 and 19.

The clutch-shaft 17 is provided at its ends with sliding clutch-sections33 and 34, which are adapted to interlock with clutch-sections 35 and 3Gof shafts 37 aud 38, disposed in alinement with the clutch-shaft andcarrying the side drums 10 and 11. The sliding clutchsections 34, whichare connected with the clutch-shaft by keys or feathers, are operated bylongitudinal levers 3D and 40, fulcrumed between their ends on suitablesupports of the frame and extending to the rear thereof in order to bewithin easy reach of the engineer. By this construction either of theside drums may be thrown into operation when the central or main drum iscut out.

The central drivebelt has its lower Hight engaged by a belt-tightenerconsisting of a lever-frame 40,0f substantially-oblong shape, pivotedbetween its ends at 41 and having a pulley 42, mounted between the frontends of the sides and engaging the belt 2J: at a point adjacent to thedrive-wheel The rear end of the Frame is provided with a suitable weight43, which maybe varied to obtain the necessary power.

The side belts, which connect the clutchpulleys with the front pulleys,are engaged by belt-tighteners 44:, constructed similar to that beforedescribed,being provided at their front ends with loose pulleys oridlers and having suitable weight-s at their rear ends. Thebelttighteners il, which are fulcrumed beneath the clutch-shaft, arelocated in the spaces between the longitudinal beams of thesupporting-frame.

The side cables are attached to the main cable accordingly as the logslie to one side ofthe apparatus or to the other, and this coupling maybe effected by any suitable means, such as a hook 45 and an eye 46. Inorder to prevent the central and side drums from rotating too rapidlyand paying out the cables too, fast when they are free to rotate,bandbrakes 47, 448, and if) are provided, and each band-brake consistsof a strap or band passing around the drum and having one end secured tothe main frame, and its other end is connected with the operatingmechanism hereinafter described The band-brake 47 is' connected by a rod50 with a rock-shaft 51, which is controlled by a suitable handle orlever 52. The band-brake 48, which is arranged at one side of theapparatus, is connected by a rod 53 with one arm of a rockshaft 54, andthe latter is connected by a short rod 55 with an operating-lever 5G.The rockshaft 54, which is disposed transversely of the frame, extendsfrom the space in which the drum 10 is mounted to the space between theadjacent longitudinal beams 12 and 13. The band-brake t), which islocated at the opposite side of the frame, is of the same constructionas the band-brake 48 and is connected by a short longitudinal rod 57with a transverse rock-shaft 58, provided at its inner and outer endswith arms, the inner arm being connected by a rod 59 with anoperating-lever GO. The operating-levers of the bandbrakes are arrangedadjacent to one another and are within easy reach, as will be readilyapparent.

It will be seen that the apparatus, which is sim plc and comparativelyinexpensive in construction, possesses great strength and durability,that itis adapted to dispense with gearf ing for communicating motionfrom one shaft to another, and that the belt connections between thcshafts produce a steady strain on the cable, so that the apparatus maybe run at a right rate of speed without liability of injuring the cable.It will also be apparent that a reeiprocatory carrier maybe provided ateither side of the apparatus and that the latter is readily controlledto cause the side cable to run out the central or main cable after aload of logs has been hauled in. Furthermore, it will be clear that thebelts are maintained at the proper tension and that the drum, which isloose, is prevented from being rotated too rapidly, so that the cablebcing unwonnd will not slacken and become tangled.

Changes in the form, proportion, size, and

the minor details of construction within the scope of the appendedclaims may be resorted to without departing from the spirit or sacri-Iieing any ofthe advantages of this in veution.
